Benchmark points for Higgs-to-Higgs cascade processes in the NMSSM have been proposed in
[1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, see also the twiki web site of the LHC-HXSWG3-NMSSM working group [15]}.
However, earlier benchmark points are often outdated due to more recent limits from searches in the proposed (or other) channels.
